Product details
Overview
MAX6062BEUR-T from Maxim Integrated is a precision, low-dropout, micropower 2.048V voltage reference in a 3-pin SOT23 package. It delivers ±0.39% initial accuracy, 20ppm/°C max temperature coefficient, and supports 5mA source / 2mA sink load current. Designed for high-accuracy ADC biasing in portable instrumentation and battery-powered data acquisition systems.
For engineers reviewing the MAX6062BEUR-T datasheet, MAX6062BEUR-T pinout, MAX6062BEUR-T application, or MAX6062BEUR-T equivalent, key selection criteria include its 2.048V output (ideal for 12-bit SAR ADCs), ultra-low 90µA quiescent current, 200mV max dropout at 1mA, no external capacitor requirement, and guaranteed performance across –40°C to +85°C.
Technical Context
The MAX6062BEUR-T is a three-terminal series-mode voltage reference featuring proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its BiCMOS process enables stable operation without external compensation while maintaining supply-current independence (≤8µA/V variation) across 2.5V–12.6V input range.
It achieves 130ppm output voltage hysteresis and 62ppm/1000hr long-term stability, with dynamic performance including 22µVp-p (0.1Hz–10Hz) noise and 86dB ripple rejection at 120Hz. Turn-on settling time is 115µs to 0.1% of final value with 50pF load capacitance.

FAQ
What is the output voltage tolerance of MAX6062BEUR-T over temperature?
The MAX6062BEUR-T guarantees ±0.39% initial accuracy at +25°C and a maximum temperature coefficient of 20ppm/°C across –40°C to +85°C. This results in total output variation of ≤±0.55% over the full temperature range, calculated as initial error plus worst-case drift. The MAX6062BEUR-T datasheet confirms this performance under specified load and line conditions.
Does MAX6062BEUR-T require an external output capacitor for stability?
No, MAX6062BEUR-T is internally compensated and remains stable with 0pF output capacitance. An optional 0.1µF ceramic capacitor may be added to improve transient response when driving step loads, but it is not required for frequency stability. This eliminates BOM cost and saves PCB area - a key advantage confirmed in the Applications Information section of the MAX6062BEUR-T datasheet.
What is the minimum input voltage needed for MAX6062BEUR-T to regulate properly?
The MAX6062BEUR-T requires a minimum input voltage of 2.5V to maintain regulation, as specified in the Selector Guide and Electrical Characteristics tables. At 1mA load, the dropout voltage is ≤200mV, meaning VIN must exceed VOUT + 200mV = 2.248V - but the guaranteed specification starts at 2.5V to ensure performance across process, voltage, and temperature corners. This is explicitly stated in the MAX6062BEUR-T ordering information and absolute maximum ratings.
Can MAX6062BEUR-T sink current, and how much?
Yes, MAX6062BEUR-T can sink up to 2mA of load current, as verified in the Load Regulation and Output Short-Circuit Current specifications. This bidirectional capability allows it to actively pull down the reference node during dynamic load transitions, improving settling time and reducing output overshoot - a feature critical for driving switched-capacitor ADC inputs or precision DAC bias networks. The MAX6062BEUR-T datasheet confirms this in both electrical characteristics and typical operating circuits.
How does MAX6062BEUR-T compare to shunt voltage references in terms of supply efficiency?
Unlike shunt references that waste supply current through a series resistor, MAX6062BEUR-T draws only 90µA quiescent current independent of input voltage (≤8µA/V variation). This eliminates wasted bias current and enables efficient operation across wide input ranges (2.5V–12.6V), extending battery life in portable systems. The MAX6062BEUR-T datasheet explicitly contrasts this architecture against conventional two-terminal shunt devices in the General Description section.
